[ Upstream commit67e2996f72] Each GPIO bank supports a variable number of lines which is usually 16, but is less in some cases : this is specified by the last argument of the "gpio-ranges" bank node property. Report to the framework, the actual number of lines, so the libgpiod gpioinfo command lists the actually existing GPIO lines.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
